Lithium power battery is mainly used in various vehicles, ships, aircraft and other internal combustion engine start, lighting, storage, uninterrupted power supply, mobile communication, portable power tools, electric toys.

In recent decades, due to the rapid development of transportation, communication and computer industry, the product series, product types and product performance of power battery have undergone great changes to meet the needs of different USES. The cross-use or substitution of all kinds of power batteries is becoming more and more frequent.

In the context of the development of domestic, current and power lithium ion battery into competition of similar products mainly include fuel battery, supercapacitor, lead-acid battery, nickel metal hydride batteries and solar cells, and iron nickel cadmium nickel battery, battery, metal oxide batteries, zinc, silver, zinc nickel battery, nickel metal hydride battery storage battery is also in the field of some traditional formed certain threat to the development of power lithium batteries. During the "two sessions" in March 2010, the support policies for new energy vehicles once again became the focus of the market. It is predicted that from 2010 to 2013 is the rapid growth period of lithium battery electric vehicles, with an average annual compound growth rate of 124.78%, and surpassed nimh battery electric vehicles in 2012. This provides a once-in-a-lifetime opportunity for domestic battery manufacturers. Domestic and foreign companies should make use of their own technological advantages to accelerate the industrialization process of power batteries with independent intellectual property rights and strengthen and expand the new energy industry.
